I'm 8 weeks and I've been spotting for the last 2 weeks, but today it is more than spotting, it's almost look like a menstrual cycle, but just when I use the restroom. I did use a panty liner today and a little blood did go onto that. Should I be worried and go to Urgent Care or just wait and see if it persists tomorrow? I go to my first OB appt on Tuesday.... I am so worried.
